i am trying to post the content of wireless setup file to you but i get this message " You are only allowed to post URLs to other sites after you have made 15 posts or more. " so what should i do in this case

You have two drivers loaded for the wireless, the b43 and the wl driver. This will cause the wireless to not function. In most cases the wl driver would be considered the better one to use, but in your case, you have another thing to consider.

The b43 module uses a helper module named ssb. The ssb module is also used by your wired connection driver b44. To use the wl wireless module you would need to remove the b43, b44 and ssb modules. This would make your wired connection non-functioning, ever.

So, the best thing to do is remove the wl module, install the firmware and use the b43 driver. If you ran the b43-fwcutter program earlier, and said yes when it asked to download and install the firmware, then you just need to do this.

Code:

sudo modprobe -r b43

Code:

sudo modprobe -r wl

Code:

sudo modprobe b43

That should get your wireless to work. Let us know how things are, and if OK, we can make a more permanent fix.

EDIT: I see from the info in that you provided that the firmware isn't installed. Run this command:

Doing a "clean" install will most likely end in the same result. You need the ssb module for your wired internet connection. To use the wl module, you have to remove the ssb module. That is why you must remove the wl wireless module and use the b43 wireless module instead. To use the b43 module you must also install the needed firmware.

This is what you must do in order for both the wired and wireless connections to work. You will have the same problem on any other version of Ubuntu. Possibly using a different distro will give you better results. Try using Fedora 11, you will still need to install the firmware. You can download a .rpm file containing the firmware from here:

it didn't work , i am wondering why i am not able to manually figure ( or add ) a wired or wireless Internet without all these commands ... it is really a remarkable drawback for naive customers or end users as connectivity is their main primary endpoint ...
thanks and i think it is time for ubuntu 9.04 unless you are gonna to you suggest something else ?

When manually unloading/loading modules, You can't reboot and expect it to work. rebooting will load the default modules. If you find a configuration that works, we can modify which drivers will load, and prevent some from loading entirely.

Try Ubuntu 9.04 as a LiveCD, and see what you get. Use the commands from this thread to diagnose it.
